Train AI models
for real world robots.
The quickest way to start training AI models on a real world robot.
Get a robot arm that just works out of the box.
Join the hundreds of SO-100 users. A dynamic community of builders for tips, support, and datasets.
Hack it, break it, fix it. The SO-100 design of the robot arm is open source with accessible spare parts.
We assemble, calibrate and test the robot arm in our office in Paris, France.
100% LeRobot and HuggingFace compatible. Start fine-tuning models with LeRobot by Huggingface 🤗
